ICP Gas Valve Support Bracket for RGS121SEAB0AAAA — OEM Mount | Ships Today

Overview

This OEM gas valve support bracket (part #1178238) secures and stabilizes the gas valve assembly in the ICP / Tempstar / Heil RGS121SEAB0AAAA gas furnace. The bracket holds the valve and manifold in proper alignment so the burner orifices stay correctly positioned and so the gas piping isn't stressed by vibration during ignition and blower operation. A bent, corroded, or missing bracket lets the valve and manifold shift, which can cause flame rollout, uneven burner ignition, or strain on the gas line connections. Replacing the bracket restores a rigid, factory-correct gas valve mount.
